摘要

Azido energetic compounds are important components of primary explosives because of their excellent initiating ability. However, azido-group installation in energetic molecules usually relies on hazardous reagents such as NaN₃. Herein, we report an atom-economical azido-group installation strategy based on an intramolecular Dutt-Wormall-type process that requires neither an external azide reagent nor an additional amine source. Using this approach, azido-containing energetic compound ATPTT was synthesized, showing excellent detonation performance (D_v = 9217 m/s) together with acceptable thermal stability (147 °C) and sensitivity (IS = 3.5 J; FS = 40 N). This work offers a new route to azido-functionalized nitrogen-rich energetic heterocycles and highlights its value for the development of high-performance primary explosives.
